Specification of Letters Patent.

Patented March 5, 1907.

Application filed September 8,1904. .Serial No. 223,780-

.To .ctZZ whom it play concern:

vBe it known that l, HIRAM l/V. BLAIsDELL, .a-citizen of the United .States,..residing at Los Angeles, in the county oflios .Angeles and,

State'of California, have invented certain new and useful Improvements in Transfer Mechanismgandl dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

This invention relates to machines or apparatus for efiecting the transportation or.

transfer of mechanical appliances or machines in entirety, and particularly to the transfer ofmachines from one-operativeposition to another; and some of the objectsof the invention are to produce mechanical means of this general character which will be simple and :cheap in construction and positive and efficientin operation.

Another objectof the invention is to produce means for transporting or transferring machinery used to operate upon or cleanse covered filtration plants orrsystems, so that thefield of usefulness ofa treating or cleans- .ingmachine will be greatly enlarged and the .cost of treating or cleaning afiltration plant correspondingly reduced.

Another object of theinvention is to provide means for efiecting the transportation of machines-or apparatus from one place of operation of the latter to another place distant therefrom and to effect such transportation in a rapid andefficient manner withsthe minimum amount of manual labor.

Itisalso an objectofthis invention to proviie a housing orprotection for the treating Of this application, in which Figure l :is an end elevationalyiewof-the machine or mechanism, showlngportlons-i'of lines.

Fig. 2.is side elevational view ofthe same. .Fig. .3 ista top plan view of the transfer-table shown in Figs. 1 and 2. Fig. .4 is a detail side elevational view of the same, showing parts ofa filter-cleaning or .other machine dotted Fig. 5 is an endelevational view of the construction illustratedin Fig. .4. Fig. 6 isa top plan view of the gauntree-crane, showing the propelling and operating mechanism.

Fig. 7 illustratesthe hanger-frame and transfor table in inoperative position in the Fig. 8 shows one construction ofclosed filter-bed with which the invention is designed to be used, and Fig. 9 .isa detailed view of the hanger-frame.

Similar characters of reference designate corresponding parts throughout the several views.

This invention is particularly designed and constructed for use in connection with filtration plants or water-filtration works,

and especially with that subdivision or class thereof generallyknown as covered. filters, which are generallyemployed to avoid the difliculties lnherent to keeping the filters operatingprcperly duringcold weather, caused by the disturbance of the topsurface of the sand. during the removalof the ice, the freezing ofthe-surface after scraping, and the necessity of cleaning certain portions of the filters more frequently than the remainderof the area, resulting inabnormally high rates of filtration on the parts so cleaned. Covered filters also prevent the growthiofalgae, which produces rapidsurfaceclogging on the filters in summer weather, and seeimentation is facilitated by theabsence oflight and wind.

The shape of filter-beds is generally rectangularin plan, and they are usually arranged in a plurality of parallel rows, which are generally covered by grcined .arches springingfrom the tops of columns or piers, because ofthe ease with which they may be constructed of brick, ,masonry, or concrete. Covered filters have many columns, piers, buttresses, &c., which pass through thefiltering materialsand interrupt the surface of the filter, thereby rendering muchmore difficult the operation of cleaning, scraping, or treating the filtering material.

,To effect the transportation of "a filtercleaning machine from oneset ,or group-of filter-beds toanother, and to effect the transfer of such machine from one row or series of filter-beds to another, and to accomplish the foregoing objects in a cheap, simple, and efficient manner are the principal points of this invention. Therefore, referring to the drawings, and particularly to the construction illustrated in Figs. 1 and 2 thereof, the reference character 1 designates a portion of the groined or other cover or roof of a covered slow sand filtration plant or works before mentioned, and the cover or roof 1 is preferably supported upon piers or columns 2, substantially as shown, while a manhole or trapdoor 3 is desirably formed in the roof 1 at one or more suitable places therein, through which the cleaning or other machinery may be introduced into and withdrawn from the filter. Tracks or ways 4 are preferably located upon theupper surface of the roof or cover 1 on each side of the opening or trapdoor 3 and are adapted to receive the supporting-wheels 5 of a gauntree-crane or traveling structure 6 of any preferred construction. Preferably upon the top of the gauntreecrane is mounted a motor 7 or other actuating device, having a driving-pinion 8, meshing with a driven gear 9, having a double clutch-hub loose on an actuating-shaft 10, carrying beveled pinions 11, engaging simi lar pinions 12 on screw-actuating shafts 1.3, each carrying beveled pinions 14, meshing with similar pinions 15, mounted upon the upper end of the vertical screws or threaded rods 34, preferably revolubly mounted in each corner of the gauntree-crane, substantially as shown.

By means of the mechanism just described the depending or hanger frame, the

transfer-table, and the filter-cleaning or other machine may be raised within the gauntree-crane and transported therewith from one place of operation to another or lowered therefrom into operative position substantially as hereinafter described.

To effect the propulsion of the gauntreeframe, a gear-wheel 17 is loosely mounted upon the actuating-shaft 10, having a clutchhub constructed to engage with the similar hub on the gear-wheel 9, so that when in such engagement the wheel 17 is driven by the driving gear-wheel 9, which is thus out of driving engagement with the shaft 19, or the drivingv gear-wheel is thrown in one direction to operate the elevating and lowering mechanism and in the other direction to operate the propelling mechanism. The gearwheel 17 preferably meshes with a similar wheel 18 on a counter-shaft 19, carrying a bevel-pinion 20, meshing with a like pinion 21 on a short shaft 22, carrying a bevel-pin ion 23, engaging a similar pinion 24 on a vertical shaft or propelling-rod 25, carrying a beveled pinion 26, meshing with a like pinion 27 on a propelling-shaft 28, having a pinion shaft 31, carrying a pinion 32, meshing with a gear-wheel 33 on the shaft of one of the supporting-wheels 4 of the crane.

Each of the screws 34 has threaded connection with a depending or hanger frame 35, of suitable construction, preferably provided with sections of tracks or short supporting-ways 36, desirably extending in approximately the same direction as the tracks 4 upon the cover of the filter, and the tracksections 36 are adapted when the hangerframe 35 is lowered, as shown in Figs. 1 and 2, to register with and fill out or complete the tracks or supporting-ways 37, formed on or connected with each side of the upper portion of the piers or columns 2 and preferably extending longitudinally of the filter-bed and along one side thereof.

Referring to the construction illustrated in Fig. 2 of the drawings,it will be seen that the tracks 37 do not extend entirely across the filter-bed, but only as far as the opening or trap-door 3 in the roof or cover of the filter, substantially as shown in Figs. 1 and 2 of the drawing, in order that the lowering of the hanger-frame 35 into said opening will complete the tracks 37 by means of the tracksections 36, carried by said frame, as will be readily understood by those skilled in the art to which this invention appertains.

A transfer table or frame 38 is preferably mountedon supporting devices or wheels 39, Figs. 1 to 5, adapted to be supported by and travel on the track-sections 36, carried by the hanger-frame35 and the tracks 37, supported from the columns or piers 2, whereby the transfer-table 38, with the cleaning or other machinery supported therefrom, as shown in dotted lines in Fig. 4, can be transferred from one gallery or row of arches to another to, permit the use of such machinery in each gallery.

The trans..ertable 38 is preferably proelled over the track-sections 36 and the tracks 37 by means of a motor 40, having a driving-pinion 41, meshing with a gear-wheel 42 on a worm-carrying shaft 43, the worm whereof engages a worm-wheel 44 on one of the propelling-shafts 45, rigidly connected with two of the supporting-wheels 39 of the transfer-table 38, substantially as shown in Figs. 3 to 5 of the drawings. The motor 40 pre.'erably receives power or electricity from trolley or feed wires 46, Fig. 2, desirably extending along one side of the filter-bed, substantially in the same direction as the tracks 37, and the hanger-frame 35 preferably carries a section 47 of, trolley or feed wire to complete the wire 46 when the hangerframe is in operative position, substantially as shown, and trolleys 48 are preferably mounted on the transfer-table 38 to take the current from the wires 46 and 47 and deliver the same, through suitable electrical connec- 29 engaging a gear-wheel 30 on a counterl tions, to the motor 40.

sas es or other machinery may take power.

The operation of this invention be readily understood from the foregoing description When taken in connection with the accompanying drawings and the following explanation thereof. When it is desired to; clean or operateupon aclosed filter, the gauntree-crane, With the hanger-frame 35, p the transfer-table 3'8, and the cleaning machin' ery then elevated thereint'o, is progressed along the tracks 4 upon the roof or cover of the inter until the crane and its contents are over the opening or trap-door 3 in said roof, 1

such propulsion being effected through the motor 7, (supplied with power any suitable manner,) pinion 8, gear whee'l shaft 10, 'gear wheels 17 and 18, counter -'shaft 19, pinions 20 and 21, shaft 22, pinions 23,

and 24, propelling rod 25, pinions 26 and 27, propelling-shalt 28, and chain of gears to shats of supporting-Wheels 5, as beiore de- The gauntree-crane and contents being thus in position above the roof-opening, the propelling mechanism is stopped,

and the elevating and depressing :mechanism is started by throwing the clutch device out of engagement With the propelling mechanism and into engagement with raising and lowering mechanism, whereby "the hangerframe 35, transi'er-table 38, and cleaning or other machine are lowered into operative position, substantially as shown in Figs. 1 and 2' of the drawing, whereupon the transfer-table 38 and machine supported there romcan be moved upon the track-sections 36 on the hanger fram'e 35 and on the ra'ils37 across the fil:ter-bed,'so that the machine can be stopped inany gallery or row of arches wherein it is desired to operate the machineywhich Will then be moved trom the rail-sections 500i the transfer ta'ble onto the rails 51 upon the columns or piers 2, as Will be readily understood.

Although this inventionhas been described and shown in'connec'tion with covered filtration plants, yet it is not intended tO-limit or confine the same tosuch use, as theinvention was thus disclosed merely as anapplication thereof, for the invention is equally capable and applicable to many other uses or in vari-ous other connections.
